----------------------------------

             Summary: createDataResource will sometimes fail when uploading Excel documents due to missing libraries
                 Key: OFBIZ-7899
                 URL: https://issues.apache.org/jira/browse/OFBIZ-7899
             Project: OFBiz
          Issue Type: Bug
          Components: content
    Affects Versions: Release Branch 15.12, Trunk
            Reporter: Forrest Rae


createDataResource calls org.ofbiz.content.data.DataResourceWorker.getMimeTypeWithByteBuffer().  getMimeTypeWithByteBuffer calls into the Tika library to detect the mime type of the file.  Tika will try to detect the file format, leveraging a number of detectors, one of which is Apache POI.  Apache POI's detector will try to call routines in jar files that are not included in with the content application, leading to the following exception:

java.lang.IllegalAccessError: tried to access method org.apache.poi.util.POILogger.log(ILjava/lang/Object;)V from class org.apache.poi.openxml4j.opc.PackageRelationshipCollection

The missing jar files can be found here:
https://archive.apache.org/dist/poi/release/bin/poi-bin-3.13-20150929.zip

The missing jars are:
poi-ooxml
poi-ooxml-schemas

Might be good to update to the latest version of POI as well:
